ABSTRACT
Objective To investigate the clinical value of hysterosalpingo-contrast-sonography (HyCoSy) with high-pressure syringe injection and time-intensity curve analysis in the diagnosis of women infertility due to tube obstruction.Methods Fifty-six women with infertility underwent HyCoSy with compressive injection of SonoVue with a balloon catheter and high-pressure syringe.Time-intensity curve based on Autotracking Contrast Quatification (ACQ) software was analyzed in all patients.The arrival time (AT) of microbubbles from uterine cavity to tube fimbria was analyzed between partially obstructed tube group and control group.Results The AT in the group of partially obstructed tubes was (3.49 ± 1.70) s,while the AT in the group of freely patent tubes was (1.14-± 0.37)s,there was statistical difference of AT between the group of partially obstructed tubes and the group of freely patent tubes (P =0.000).According to ROC results,the optimization point of AT was 1.65 s,the sensitivity,specificity,positive predictive value and negative predictive value were 92.6％,93.3％,96.2％ and 87.5％,respectively.Conclusions High-pressure syringe injection in HyCoSy is useful for regular administration and high image quality.The AT could be considered as the diagnostic indices in the evaluation of fallopian tube patency for infertile women.
